Sound! Euphonium 3 - Episode 4

In Episode 4 of "Sound! Euphonium Season 3," Motomu visits a family grave, hinting at personal challenges. Meanwhile, the students of Kitauji High School, including Kumiko and Kousaka, eagerly prepare for the SunFes competition. During rehearsals, a dispute arises between Motomu and a bandmate over formalities, revealing underlying tensions beneath the surface.

At the heart of the matter is Motomu's erratic behavior over the past week, which his friends associate with recent family issues. Conversations between Kumiko, Midori, and Hazuki reveal that Motomu turned down a guaranteed spot at Ryusei High School, which gained national recognition under Gen'ichirou Tsukinaga—a name that repeatedly surfaces in connection with Motomu's past and present dissatisfaction.

During the SunFes festival, various interactions provide deeper insight into personal histories and current dynamics. Kumiko meets Sasaki, a friend from middle school, who offers her a brief respite and prompts her to reflect on her musical journey. Meanwhile, an encounter with Gen'ichirou and an overheard conversation about Motomu's family add further layers to the unfolding drama, particularly regarding Motomu's deceased sister and his strained relationship with his grandfather, Gen'ichirou.

As performances unfold, Motomu's outburst against a Ryusei High School band member escalates tensions further, ultimately leading to his apology. Discussions between Kumiko and Midori about Motomu's troubled past and current emotional state deepen, as do the intrigues surrounding Gen'ichirou's influence and its impact on Motomu's family.
